The issue is trust. People don't trust the science because they don't trust the media. Too much mis-information being posted from both sides about the virus, vaccines, treatments, testing etc. You see outlets pushing masks then see them not wearing them sends a bad message. Additionally, is it Covid that killing people or are people dying of other things and getting Covid? That's a question being posed more and more.
For the folks that are not vaccinated name calling and insults isnt going to sway them to get the shot. Making them believe there is a benefit will get them to do it. I don't think anyone really thinks Covid doesn't exist but there are growing numbers that don't trust what they are being told about it from both the media and our leaders.
Tragic and sad story.
